Abstract
2.25Cr-1Mo steel-347H dissimilar metal welded joint prepared using a nickel-based filler metal (INCO 82) as a transition joint was assessed for its oxidation and corrosion performance in a mixture containing 40% K2SO4 and 60% NaCl. Hot corrosion attack led to the formation of oxides of iron on the surface and sulphides of iron and chromium on the subsurface. © 1994.
